y RAIL-TlE. j 'i To all whom it may cori/'cern` f 'l Be it known that I,'FRANK NQ MIHILLs, a

citizen of the United States, residing at Arlin tdn Heights,-Boston,inthe county of Su olk and Stateof Massachusetts, have yinvented new anduseful Improvements in Rail-Ties, of which the following is aspecification.

.This invention relates to railway-ties, and

has for its objects to produce a comparatively simple inexpensive deviceof this character which will be exceedingly strong and duraable, one tovwhich the rails may be readily and firmly attached, onewherein spreadingof the rails, owing to. one or more of the ties becomingv fractured, isobviated, and one which in practice will be p'racticallyindei4structible through thefactionof climatic or elementalv changes.

Further objectsof the invention are to provide simple and efficientmeans for securing the rails tothe ties, one wherein the rails will bemaintained firmly and securely in place, and one vwhereln the ties will,to a mea-surable extent, be relieved ofthe vibrations to which the railsare in practice subjected.

With these and other objects-in view the.

f invention Vcomprises fthe novel features of 3o fully hereinafterdescribed.

It will be observed, i

however, that should the tie i`n` practice being to its peculiar form,serve to securely bind 75 i come broken'the binding member 2 will, ow-

together the'p'ortions of the tie and prevent j Securedv tothe tie. l'bymeans of enga ing members or clips 8, in turn retained in p ace byfastening members or bolts 9, is-a pair of i rails 10 of usualconstruction and arranged in -1 lthe customary's aced arallelrelation,-there bein arranged! eneat each of the rails and to w olly-cover lthe -adj acentnportionof the ti'ea steel 0r ,othenmetalwear-plate 11, between which and'the tie there'is in turn'situf ated acushioning member or plate 12, of 'l 9. `sive in area withthe platen 1 1and serves in practice to relieve the tie of vibrations inci Ident .tothe rails, these plates bein secured wood for fibrousmaterial, ywhich iscoexten infplace by means of the bolts 9, w 'chpass throu h suitableopenings 12( in the plates. f'

x Em ed'ded in.. the tie 1 -at appropriate points are metal boxes 1'3,constituting sock-I ets to receive thebolts 9', and each havingvat itslower end semicircular enlargements 14 and r15. of unequal'heights andpresentingv` shoulders or'abutments 16 l17, disposed at relativelydifferent' vertical elevations, these shoulders bein-g designed forengagement by an angular engaging portion 18 ormed lat the lower end ofeach of the bolts 9, While upon the 'upper Yendsl of the latter and in.

threadedengagement therewith are nuts 19,

designed for engagement, as usual, with the engagement with thebase-flanges of the rails,

clampingplates -to hold the latter in secure,` I IO izo i understood inthis connection that .aside of the shoulders in the socket by means ofkeys or wedges 20, which are entered vertica ly into the socketsincontact with the respective bolts It is to be noted in this connectionthatthe openings 12 are of a size toA recelve not only the bolts 9, butalso the up er ends of the wedges 20, which are of suita le 'length toproject into the openings.

In practice the bolts 9 are entered into the bolts 9, of suiiicientcross-sectional area to wholly ll the body portions of the sockets 13.The bolts having been placed in position, plates 11 and 12 are nextpositioned andthe 'rails 1 0 seated thereon, after which the plates 8are seated upon the bolts and secured by means of the nuts 19. In theevent of it becoming necessary or desirable to lace a greater number ofplates 11 or 12 eneath either of the rails for leveling the latterrelatively the lower portions 18 of the bolts are engaged With theshoulders 17, the bolts being thereafter `securedb means ofthe keys 20in the manner hereto ore explained, this arrangement 'of the parts beingpossible owing tothe fact that the openin" s 12 are of a size to receivethe bolts 9 and a so the ends of the wedges 20, whereby the bolts 9 maybe moved to the inner endsof the openings 12 and the wedges introducedat the outer ends of the latter `for holdin the bolts in place.

In Fig. 9 is illustrated a slight modification of the device, in whichthe tie employed at the joint between a pair of rails is formed witheXtra wide ends, the meeting ends of the rails being secured to said tieby means of the clips 8, held in place by bolts 9, which in turn areentered intov metal boxes in the tie and held by means of fastening keysor wed es in the manner heretofore explained, it eing from forming 'thetie with extra wide ends to accommodate'the meeting ends of the railsthe construction and operation of the parts are identical with thoseabove described.

. 5o From the foregoing it is apparent that I.

produce a simple inexpensive tie which in 4what is c aimed as new is- 1.An artificial-stone tie having a binding member embedded therein, saidbinding member comprising a longitudinal bar and end engaging portions,and a brace attached to the bar and comprising opposite u per and lowertrusses and spacing members Ibetween the trusses and bar.

2. An/artiiicial-stone tie having va binding member embedded therein andcomprising a pair of spaced arallel bars and end portions connectingsaid bars, a brace upon each of the bars adjacent the longitudinalcenter of the tie, said brace comprising upper and lower trussesattached to the bar, and spacing-blocks between the trusses and bar.

v3. A tie provided with a socket having a pair of shoulders disposed atcomparatively dierent elevations, a rail seated upon the tie, a platearranged beneath the rail and fastening means for the rail' andplateincluding a bolt having. an angular ortion ada ted for engagingwith eit er ofP said shoul ers, and a wedge entered into the socket incontact with the bolt for maintaining said angu- `lar portion andshoulder in engagement.

In testimony whereof I affix my signature 1n presence of two witnesses.
